EXPANDING DIE.

Specification of Letters Patent.

Patented July 26', 1921.

Application filed September 18, 1916. Serial No. 120,592.

siding at Milwaukee, county of Milwaukee,

and State of Wisconsin, have invented new and useful Improvements in Expanding- Dies, of which the following is a specification.

My invention relates to improvements in expanding dies.

The object of my invention is to provide means for expeditiously clamping and shaping metallic mouth pieces upon non-metallic receptacle walls and particularly for clamping metallic mouth pieces upon the tapered walls of paper bottles.

In the drawings- Figure 1 is an elevation, partly in vertical section, of an expanding die and clamping mechanism embodying my invention.

Fig. 2 is a plan view of the same, showing also a fragment of the chute through which the mouth pieces are fed to the machine, with dotted lines indicating the mouth piece feeding arm in retracted position preparatory to a feeding operation.

Fig. 3 is a plan view with the table and feeding mechanism removed to show the clamping devices and expander.

Fig. 4 is an enlarged fragmentary view in vertical section, showing the expander and clamp in a position to receive the mouth piece and also showing a mouth piece in position thereon.

Fig. 5 is a similar view, showing the parts in operative position for clamping and expanding the mouth piece into engagement with the walls of a paper bottle.

Fig. 6 is a rear elevation of the lower por tion of the machine, showing the driving and controlling mechanism.

Like parts are identified by the same reference characters throughout the several views.

A table, having upper and lower top members 1 and 2 respectively, is supported from a base 3 by a standard which is formed in telescoping sections 4 and 5 respectively, the upper section 4 being tubular in form and the two sections being adjustably secured together by one or more set screws 7.

The expander.

Within the upper section 4, expanding die members 10 are arranged in an annular serles. Each of these members is supported by a shank 11 from a base 12 which is fitted to the interior of the member 4 and secured thereto by a set screw 13. The shanks 11 are preferably integral with the base ring 12 and they are formed by slitting the sleeve 12 Vertically. The shanks 11 are exteriorly reduced so that the expander jaws 10 may be spread. A downwardly tapered conical spreader 17 is fitted to the interior surfaces of the spreader jaws 10, said surfaces being also preferably formed so as to converge downwardly to form anelongated bearing for the cone surfaces of the spreader 17. The spreader is provided with a tubular shank 18 through which an operating rod 19 passes. This operating rod is provided with a head 20 at its upper end socketed in the spreader cone 17 and pocketed therein by a nut 22 having threaded engagement with the walls of the socket. The operating rod 19 is enlarged at its lower end and the enlarged portion 24 is fitted to the walls of a socket 25 formed in the upper end of the lower standard section 5.

A cross pin 27, connected with an exterior sliding collar 28, extends through slots 29 in the standard section 5 and also through the enlarged portion 24 of the operating rod 19. This enlarged portion 24, being fitted to the walls of the socket 25, not only constitutes a guide for the lower end of the operating rod 19, but also provides a substantial connecting member for the cross pin 27 through which motion is transmitted to the operating rod 19 and expander cone 17 from the exterior collar 28. The collar 28 is actuated downwardly by a lever 30, the motion of which is transmitted to the collar through rods 31. Lever 30 is pivoted at 32 to a bracket 33 connected with the lower standard section 5 by a collar 34. Lever 30 is normally held in a raised position by a Y wardly to normal position,

witha pedal 38, whereby it may spring 36 which'connects the lever with a standard bracket 37. Lever '30 is provided be actuated downwardly by the foot of the operator, thereby drawing collar 28 downwardly and transmitting motion through cross pin 27 and rod 19 to the expander 17. The socket which receives the head 20 of rod 19 is preferably elongated so as to allow a slight downward movement of lever 30 before actuating the spreader cone 17.

.The feeding mechanism. The metallic mouth pieces to be secured "to the walls of the tapered bottles are fed to the machine through a chute 40,'the lower end of which is substantially horizontal and extends across the upper surface of table member 1 at a tangent to a circle described from the center of said table exterior to the expander. The mouth pieces are pushed through the chute 40 by their own weight or from any suitable feeding means (not shown). The feeding movement,however, is normally arrested by a stop lever 41 pivoted to the upper surface of the table at 42 and having a rounded and partially elbowed extremity 43 which normally occupies a position in line with the mouth pieces at the delivery end of the chute and in such a position that the end mouth piece will strike the lever portion 43 before being fully discharged from the chute. -This lever may be swung outwardly, however, as indicated by dotted lines in Fig. 2, whereupon the mouth piece will be completely delivered from the chute to the positlon, also indicated by dotted lines in said figure, and the portion 43 of said lever 41 will thereupon engage against the outer margin of the mouth piece in such a position that when the lever swings inwill be pushed to the center of the table, where it will drop through an aperture 47 and be received upon the expander 10. The latter engages in the mouth piece, as clearly shown in Fig. 4, where a mouth piece will be observed resting u the upper end of standard section 4, with an inturned flange bearing upon the top ends of the expander members 10. A spring 49 connects lever 41 with the top of the table and tends to hold said lever in its normal position, as indicated by full lines in Fig. 2, in which position the portion 43 of the lever serves as a stop to prevent mouth piece deliveries from the chute 40. I

The table top is provided with a guide for inverted paper bottles. Qne section 50 0 this guide is bolted to the top of the table at 51. The other section 53 is hinged to the section 50 at 54. This section is shorter and its lower end is supported sufiiciently above the table to allow the mouth pieces to pass underneath it to a position where such month piece they will drop through the table aperture 47. The lower portion of the guide section 53 is connected-by a link 55 with a plunger 56 operating in a cylinder 57, from which air may be exhausted through a tube 58. This tube is connected with a vacuum chamber 59 located at. any convenient point. slide valve 60 ported at 58' is employed to admit air to the cylinder 57 in one position and in another position to exclude air from said cylinder and simultaneously connect the same with the exhaust pipe or duct 58. This valve is connected with an operating rod 61. It is normally held in a depressed position, adapted for the admission of air to the cylinder 57 through port 62, by means of a spring 63. The valve is raised to connect up exhaust duct 58 by means of a lever 65 pivoted to standard section 4 at 66, and provided with a downturned arm 67, the extremity or pad 68 supported substantially parallel to the standard and adapted to .be pressed inwardly by the body of the operator to raise the valve 60. When said valve is raised, the vacuum formed in cylinder 57 causes plun er 56 to move into the cylinder. This motion is transmitted to swing the guide section 53 outwardly away from section 50, thereby enlarging the opening to release a paper bottle, such as indicated at B in Fig. 1. This outwardly swinging movement of section 53 is transmitted to lever 41 through an arm 70, connected with said sec tion 53, and an arm or post 71 connected with the lever 41. This movement swings lever 41 to the position indicated by dotted lines in Fig. 2. Therefore when the operator is about to insert an inverted paper bottle B into position to receive one of the ,metallic mouth ieces', he first presses upon the pad or plate 68 to shift the valve 60. Member 53 is thereupon pneumatically retracted or swung outwardly upon the hinge 54, as above explained, and lever 41 is swung outwardly to the position indicated by dotted lines in Fig. 2. The operator then relieves the pressure upon the pad or plate 68, whereupon valve 68 returns to normal position, disconnecting the suction duct and relieving the vacuum in cylinder 57. Spring 49 thereupon actuates lever 41, pulling the latter to normal position, forcing the engaged mouth piece inwardly to a point where it will drop through the table aperture 47 and also transf serted in the guide, which will direct the lower end of the bottle into engagement with the groove a of the mouth piece A.

i The clamping devices.

of which is provided with a-plate 2. These jaws are provided with slots 76 through whlch bolts or screws 77 may pass to connect the table top members with each other. These bolts or screws 77 are preferably provided with anti-friction rollers 78. In addition to the slots 76, the jaws are provided with intermediate slots 80. Jaw operatlng levers 81 pass upwardly through slots 82 in the lower table top member 2 and loosely engage in these jaw slots 80, whereby the jaws may be pressed inwardly to clampmg position in an annular series. The levers 81 are each connected,at an intermediate point, by a fulcrum pin or bolt 85 with a projecting ear 86 on a collar 87 supported from standard section 4. v

The lower ends of the levers are provided with adjustable lever actuating members, comprising horizontal bolts 89 which pass through the lower ends of the levers in threaded engagement therewith, and are adapted to engage an inverted cone face 90. formed on the outer surface of the vertically movable collar 28. The arrangement is such that when collar 28 moves downwardly, this cone face 90 will spread the lower ends of the levers 81, thereby causing the upper ends of said levers to move inwardly and press the clamping jaws into engagement with a mouth piece occupying the position in which it is illustrated in Fig. 4. When collar 28 moves upwardly to normal position, the levers and clamping jaws are automatically retracted by the reaction of the compression springs 83 interposed between the upper ends of levers 81 and standard section 4. It will be observed that the clamping jaws are provided with concavely roundedsegmental faces 92 adapted to fit the curved outer marginal portion of the mouth piece A and compress the same in the direction of the lower end of a paper bottle inserted in the mouth piece groove a.

It will be observed that the clamping movement of the jaws 75 is derived from the same source as that from which the motion of the spreader 17 is derived. Therefore the expander jaws 10 v ill move into contact with the inner face of the mouthpiece member A simultaneously with the movement of the clamping jaws 75 into engagement with the outer marginal portion of the mouth piece. The mouth piece engaging portion of the expander jaws may be slightly tapered downwardly and inwardly and these.

jaws therefore will expand the mouth piece so that its inner wall will be conically tapered in conformity with the conically ta-- pered surface of the paper bottle. The clamping jaws 75 will press the outer margin of the mouth piece inwardly to only a slight extent, the. principal clamping movement being exerted by the expander members. The combined effect, however, of the clamping jaws and the expander membe s will cause the mouth piece to firmly grip the circular margin of the bottle between the outer edge margin of the mouth piece and that portion of the inner wall of the mouth lpiece against which the expander members ear. 7

After the clamping and expanding operations have been performed as above described, the operator presses inwardly upon the plate or pad 68, thereby lifting valve 60, whereupon guide member 53 will be retracted as above explained, thus allowing the paper bottle B with the attached mouth piece to be lifted and removed from the machine. Lever 41 will then be in position to insert a fresh mouth piece as soon as the pressure upon the plate 68 is removed. The operator then secures another paper bottle or blank and inserts it in the guide to receive the newly inserted mouth piece in the same manner as above explained.

For rapid operation, it is desirable that lever 30 be operated by machine power, subject to manual control. For this purpose I provide a power driven shaft 96 having a loose sleeve 97 thereon which carries a cam 98 in a position to strike the lever 30 and actuate it once during each revolution of the sleeve. The sleeve 97 may be operatively connected with shaft 96 by means of a foot treadle 99 and clutch members 100 and 101, the foot treadle being employed to shift member 100 into engagement with member 101. Spring 102 retracts the foot treadle and clutch member 100 as soon as the operator removes the foot pressure.

- I preferably interpose an auxiliary lever 105 between lever 30 and cam 98. This lever is hung upon the same fulcrum pin and its free end is supported by an adjustable member or screw 106 from the lever 30. By raising or lowering this member, the degree of movement imparted to the lever 30 by the cam, may be varied, to secure the exact length of stroke desired.
